Unable to reconstruct system from result

3

When following this [SINDy example](https://docs.sciml.ai/DataDrivenDiffEq/stable/libs/datadrivensparse/examples/example_02/), a logical final step would be to run a simulation with the discovered system of equations to inspect the result that it gives. One of...

Generating solution output for PDE takes longer than generating solution

2

Hello! I'm trying to debug an issue where I have a PDE system that takes a very long time for `solve` to run at a low point count (equivalent to...

JuliaSimCompiler doesn't work for equation system that works fine with default compiler

7

Hello, As suggested in #311, I am experimenting with using the JuliaSimCompiler to allow the use of simulations with larger point counts. I am working with a system similar to...

@parameters work unexpectedly

3

Hello, The code below is a version of the [Brusselator example](https://docs.sciml.ai/MethodOfLines/stable/tutorials/brusselator/), modified only by changing alpha from a numeric value to a @parameter: ``` julia using ModelingToolkit, MethodOfLines, OrdinaryDiffEq, DomainSets...

Units don't seem to work correctly

4

Hello, Here is a small example with units: ``` julia using ModelingToolkit, MethodOfLines, OrdinaryDiffEq, DomainSets using Unitful function ModelingToolkit.get_unit(a::Pair{Num, Float64}) ModelingToolkit.get_unit(a[1]) end @parameters x [unit=u"m"] @parameters t [unit=u"s"] @variables u(..)...

dynamic dispatch in Proj.proj_trans

5

Hello, I'm using Proj in some code where I'm trying to avoid allocations and dynamic dispatches for performance. To assist with this, I'm using the [AllocCheck.jl](https://github.com/JuliaLang/AllocCheck.jl) packages, which finds allocations...

Possible false alarm with `@ccall`?

2

[This issue](https://github.com/JuliaGeo/Proj.jl/issues/104) contains an MWE reporting a possible dynamic dispatch occuring in a @ccall function in the package Proj.jl. However, upon investigation using other methods, it was determined that there...

Observed variables are computed even when unused

**Describe the bug 🐞** I have a project that involves data loaders, basically reading large amounts of data from files and interpolating them into MTK models, for example here: https://data.earthsci.dev/stable/geosfp/....
